“…It is interesting to note that the AID of most AA decreased for pigs fed a NND diet with increasing FI levels, which is contrary to that for pigs fed a LND diet in the present study. This is in agreement with Goerke et al (2012), who observed that the AID of most AA increased as FI levels increased from 4.5 to 6% of BW for piglets fed a diet at 23% CP. A linear decrease in the AID of most AA in SBM was reported when dietary CP ranged from 165 to 255 g/kg (from adequate to excess) in the experiment of Li et al (1993).…”

“…This finding is consistent with the results of Peers et al (1977) and Smits et al (1994), who reported that the digestibility of DM and GE in barley, legume seeds, maize byproduct, and wheat byproduct was not affect by FI levels. Moreover, Moter and Stein (2004) and Goerke et al (2012) demonstrated that the digestibility of DM and GE were not influenced by FI levels for pigs fed cornstarch-based diets. Morel et al (2006) suggested that the effect of FI on nutrient and GE digestibility depends on the quality of the feed.…”

“…Apparent ileal digestibility of AA for pigs fed a normal-nutrient-density (NND) diet or a low-nutrientdensity (LND) diet at different feed intake levels (Sauer et al, 1982;Haydon et al, 1984;Albin et al, 2001). Goerke et al (2012) reported that the AID of both indispensable and dispensable AA increased as FI increased from 3 to 4.5% of BW in piglets fed a cornstarch-based diet at 23% CP. Furthermore, Moter and Stein (2004) found that the AID of Arg, Ile, Leu, Phe, Thr, Trp, Val, Ala, Cys, Gly, and Ser in SBM linearly increased with increasing FI for pigs fed a cornstarchbased diet at an 18.16% CP level.…”

“…The use of assayed digestibility values in feed ingredients to formulate diets is based on the assumption that digestibilities of nutrients and GE are not affected by FI. However, there is contradictory evidence concerning the effect of FI on nutrients and GE digestibility of pigs (Morgan et al, 1975;Sauer et al, 1982;Moter and Stein, 2004;Goerke et al, 2012).…”

“…Feed intake has a marginal or no effect on apparent ileal digestibility (AID) of AA and CP in growing pigs (Sauer et al, 1982;Haydon et al, 1984). However, Goerke et al (2012) found a reduction in AID of AA and CP as FI increased, and Moter and Stein (2004) observed that AID of most AA in soybean meal (SBM) for growing pigs increased with FI. Furthermore, a decrease or an improvement in apparent digestibility of GE with increasing levels of FI was reported by Morgan et al (1975) and Tollet et al (1961), respectively.…”

The present study was conducted to investigate the effects of feed intake (FI) and dietary nutrient concentration on the determination of apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of nutrients and GE for growing pigs. A total of 48 growing pigs (40.7 ± 1.3 kg initial BW) were surgically fitted with simple T-cannulas at the distal ileum and assigned to 6 treatment groups in a 2 × 3 factorial arrangement of 2 diets (a low-nutrient-density [LND] diet or a normal-nutrient-density [NND] diet) and 3 FI levels (3, 4 or 5% of BW per day). The experimental period consisted of a 5-d adjustment period: 2 d of feces collection (on d 6 and 7), and 2 d of ileal digesta collection on (d 8 and 9). Chromic oxide was used as an indigestible marker to calculate AID of AA and AID and ATTD of CP, ether extract (EE), ash, ADF, NDF, total carbohydrates (CHO), and GE. The AID of CP ( < 0.05), EE ( < 0.1), ash ( < 0.05), and GE ( < 0.1); the ATTD of ash ( < 0.1); and the hindgut disappearance of CP ( < 0.05), ash ( < 0.1), and most AA were affected by the interaction of dietary nutrient density and FI level. The AID of CP and the AID and ATTD of DM, EE, CHO, and GE linearly decreased for pigs fed a NND diet as FI increased ( < 0.05). Furthermore, the AID of CHO ( < 0.1) and NDF ( < 0.05), the ATTD of DM ( < 0.1), and the hindgut disappearance of CHO and NDF ( < 0.1) were influenced by FI. When pigs were fed the NND diet, the AID of most AA decreased (linear, < 0.05) with increasing FI. However, there were no linear or quadratic effects of FI levels on the AID, ATTD, and the hindgut disappearance of DM, CP, EE, CHO, NDF, ADF, and GE and the AID of most AA for pigs fed the LND diet. In summary, the AID and ATTD of nutrients and GE response of growing pigs to FI levels are dependent on dietary nutrients density. The AID and ATTD of nutrients and GE decreased for pigs fed the NND diet as FI increased.
